We are ODM and purchased a CKD kit of the NUC DE3815TYBE (only board) to integrate it on our product. We already use de 4GB eMMC to install Linux to be used as a thin client and it works very well but now we are trying to assemble and test bigger eMMC (16/32/64 GB) to test with Windows 8.1 and Windows 10. The system recognize these eMMC and we can install Linux on it without problem, but when we try to install Windows we can't. We see an error that the sytem can't boot from this drive. Could someone help me with some tip?

I'm using the last BIOS version, the OS is selected to Windows 8.1 and the eMMC is enabled. The Windows installer see the eMMC drive storage but don't allow me to install on it. The installer tells that the hardware can't boot from this eMMC drive so it can't install Windows.

On the Boot > Boot Configuration menu, in the UEFI Boot pane, OS Selection is set to Windows 8.X.

Press F10 to save and exit BIOS Setup.

Proceed with the installation of the operating system.

If the information above does not solve your problem this is most likely a compatibility problem or you can wait to see if somebody else has tried this configuration so they can explain how the operating system was installed in a bigger eMMC with this unit.Regards,Ivan

I would like to ask you since you are authorized to make changes to the Intel® motherboards, have you tried contacting an Intel representative or an embedded support group from Intel that will be able to assist you better, to be honest I’m not 100% sure if this is possible but this kind of support is not available for end users.
